Fix Broken Permissions

chmod, chown — restore access to a broken /tmp/app directory.

A beginner Linux challenge worth 3 points. Solve it hands-on in a real Linux environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: Production alert at 2 AM. The web app cannot start because someone ran chmod 000 on the config file.

Files that need fixing in /tmp/app/:

• config/app.env → must be 600 (owner read+write only — it contains secrets!)
• logs/app.log → must be 644 (owner rw, group/others read-only)
• data/db.json → must be 644 (verify it is already correct)

Commands to learn: chmod, ls -la, stat

Run check when done.
